I'm interested to know what pollen/protein cake recipes any of you guys have used, and how succesful they have been. I don't have any spare pollen at the moment, and don't want to risk contaminating my hive with purhased pollen. Therefore, I'm particularly interested in recipes that the bees accept without pollen.

I would also like to know if anyone has used more than one type of sugar in their sugar syrup, ie. glucose/sucrose/fructose, to try and achieve a broader range of carbohydrates, more similar to those provided in nectar/honey.
